Kärcher vacuum nozzle / pipe adapter

I got tired of the poor fit between the standard nozzle on my Kärcher WD6 vacuum and the standard pipe. Probably because I accidentally sanded off too much off the nozzle during heavy use. Instead of replacing the nozzle altogether, I designed this simple adapter that fits snugly into the pipe and accepts the nozzle equally snugly.

3mm thick walls - easy to adjust in FreeCAD.

Designed using unstable FreeCAD 0.22.0dev - may or may not be backward compatible.

Printed in PETG. Probably better with the flexibility that PETG yields rather than the stiffness of PLA. TPU might be another option for high durability.

I haven't used it for very long so can't attest to long-term durability.
